Paul Cook is anxiously waiting for an assessment on the injury to striker Eoin Doyle.

The country’s leading scorer, who bagged his 13th of the season and 20th league goal of 2014 in the 3-2 win over Blades, picked up a knock straight after his goal and was immediately replaced.

Cook will also have to decide what to do with regard to the keeper’s position for Saturday’s game at unbeaten leaders Bristol City.

Tommy Lee, dismissed for denying United a goal scoring opportunity, will pick up a one game ban. He was replaced by 18 year old Darley Dale born Myles Wright, who erred for Blades’ first goal, but he’s not expected to be the man that starts at Ashton Gate.

Regular reserve Aaron Chapman, 24, is on loan at Accrington Stanley and in his two games there, his first ever appearances in league football, he’s kept two clean sheets. However Cook may choose not to invoke the agreement with Stanley that enables the inexperienced keeper to be recalled early, as he may go for a more experienced alternative for the big game in the South West, with last season’s cover man Ian Dunbavin, who was ironically borrowed from Accrington, a possible option. He’s currently not registered as a player after being released from the Crown Ground in the summer and spending much of the pre-season build up at the Proact.

The game at City will be the first league game Lee will have missed since Jack Lester’s swansong in April 2013 as he nears Ray Middleton’s 250 league appearances for Spireites, the club’s second most appeared goalkeeper of all time after Ron Powell. Lee needs 11 more appearances to draw level with the man who was keeper in Spireites’ last ever game in what’s now the Championship back in 1951.
